The Modbus to PROFINET gateway BL122 is an industrial protocol conversion device designed to achieve seamless communication between the Modbus protocol (including Modbus RTUand Modbus TCP) and the PROFINET protocol. In the field of industrial automation, it can easily convert sensor and device data into PROFINET protocol and connect to PLC.
Key Features Multi-Protocol Integration
- Downlink Support: Modbus RTU/TCP (1 x RS232 + 2 x RS485)
- Uplink Support: PROFINET (Dual RJ45 ports, supports cascading)
- Full Function Code Compatibility: 01H/02H/03H/04H/05H/06H/0FH/10H
Simplified Configuration
- Web-based Visual Configuration: Log in via browser to 192.168.3.10 (default IP), username “admin,” no password required.
- PLC Managed IP: Supports dynamic IP assignment for network ports via PLC.
Industrial-Grade Performance
- Data Transfer: Max input/output 496 bytes each, total data ≤ 496 bytes.
- Communication Capability: Single serial port supports 31 slave devices; multiple interfaces support concurrent data acquisition.
- Environmental Adaptability: Wide operating temperature of -30~55℃, IP30 protection, DIN rail mounting.
Reliable Assurance
- Safety Certifications: CE/FCC/RoHS; EMC compliant with IEC 61000-4-2/4/5 Level 3.
- Dual Watchdog Mechanism: Power (PWR) + Run (RUN) dual indicator lights for real-time status monitoring.
Typical Applications
Equipment networking: connect Modbus sensors, frequency converters (VFDs), and actuators to PROFINET production lines
PLC expansion: connect Siemens S7-200 SMART/S7-1200 PLCs to collect Modbus device data
Energy monitoring: integrated electric meter/UPS, real-time reading of three-phase voltage, current, and power parameters
